Magnetic adsorbents are widely used in environmental remediation for the efficient removal of pollutants such as heavy metals, dyes, and organic contaminants from wastewater. Their magnetic properties allow for easy separation and recovery from the treated water using an external magnetic field, making the process cost-effective and sustainable. In the biomedical field, they are employed for targeted drug delivery, where the magnetic particles can be guided to specific sites in the body, enhancing treatment efficacy while minimizing side effects. Additionally, they play a crucial role in bioseparation processes, such as the isolation of proteins, DNA, or cells, due to their high surface area and selective binding capabilities. In industrial applications, magnetic adsorbents are utilized for catalyst recovery, enabling the reuse of catalysts in chemical reactions and reducing waste. Their versatility and efficiency make them a valuable tool across various scientific and industrial domains.
